Paper over the cracks, why not? Nothing is perfect. One day the house will be held together by nothing stronger than wallpaper glue and the will to stand up, so straighten up your fearless tie and stand tall.
When the wind blows everything creaks, stoke up the fire, make it crackle loudly, roar with laughter and no one will ever know. Late at night, when the guests have departed, when you are alone with memory, let every creak speak of the past when there was a lover in your bed.
Like every house, yours will fall. Soon you will be of memory only, until then let the house crack, creak, age in it's own time. The spirit that made it will return to build a new house on the land you once occupied.
Where you are going you won't need a house. Don't worry about it too much, paper over the cracks, why not?
